$55. Multiply 15 by 20 to find out exactly how much he needs for 20 weeks, which is $300. subtract 245 from 300 to find out how much more money he needs to add to his account.
Answer:
x = 50
Step-by-step explanation:
5x + 2(3x - 9) = 132 + 8x
5x + 6x - 18 = 132 + 8x
11x - 18 = 132 + 8x
11x - 18 = 8x + 132
11x - 18 + 18 = 8x + 132 + 18
11x = 8x + 150
11x - 8x = 8x - 8x + 150
3x = 150
3x ÷ 3 = 150 ÷ 3
x = 50
You would set it up: .5/100 = x/490 and then cross multiply .5 time 490 and 100 times x, and end up with: 245=100x. divide by 100, and get 2.45
